Valheim Dedicated Server - Unimplemented Opcode (D9) FE 97 60 02 40 F9 77 D9 FE 97 05 FF FF 17 1F

[highland-joe]

Running Valheim Dedicated Server on Ubuntu 20.04 (server) on aarch64, Raspberry Pi 4 (8GB)
Box64 with Dynarec v0.1.3 39f2b50 built on Aug 26 2021 10:33:55
Using Valheim Dedicated Server for Linux downloaded via steamcmd

Good news is, I got it to work, played successfully over one hour with two players on the server.

However, the server ist not stable. After several hours idle, I cannot re-connect and have to restart the server. Restart fails in about 7 of 10 attempts with the following "Unimplemented Opcode Message":

I'll attach the complete server log. Hope you can help me with this, thanks in advance.

the assertion:

Aug 26 10:39:01 raspi4 vstart.sh[13078]: * Assertion at mini-amd64.c:209, condition `amd64_is_imm32 (disp)' not met

Is because some allocated pointer is bigger than 32bits.
This is supposed to be fixed with box64 now, but it seems it still happens sometimes, and I don't know why yet.

I am having the same issue, in my case in the start of the server. I was playing some hours without issues (even if the server was online during hours without players) but the error appears when I restart it (randomly).

[tranko1]

I don't know if this can help but when I got the error I got this message:

TYPE: 31
* Assertion at mini-amd64.c:209, condition `amd64_is_imm32 (disp)' not met

Thanks a lot!

Yes, that's an assert in 64bits mono that happens when a value is not 32bits. I have fixed some of them, but not all it seems (and I'm not sure how those other occurence happens...).
I know I have to fix that eventualy.

[tranko1]

First of all: Thanks a lot for your effort!!!!!

Today I rebuild everything from the github code with the last version.
I got the previous error sometimes and sometimes (lees) I got this one too:

TYPE: 31
* Assertion at mini-amd64.c:209, condition `amd64_is_imm32 (disp)' not met

Stacktrace:

* Assertion: should not be reached at interp-stubs.c:105

But I am not if this can help you.

Hello,

With the last compilation I am getting this error:

Hey, #132 should probably fix this. Could you try it out?

[tranko1]

I tested yesterday in the night to build and run and I got the same error:

TYPE: 31
* Assertion at mini-amd64.c:209, condition `amd64_is_imm32 (disp)' not met

Stacktrace:

* Assertion: should not be reached at interp-stubs.c:105

@mogery How I can help to bring you more information?

[mogery]

That's odd. Did you pull my repo and branch correctly? You can verify by doing cat src/tools/bridge.c | grep my_mmap in the box64 directory. If it returns anything, then your pull is correct.

I'll see if I can test this locally.

[mogery]

Seems to work for me locally just fine. I got to Generating locations.

Could you maybe re-clone the repo with my edits and try building it again? Just to make sure.

git clone -b memory-map-fix https://github.com/mogery/box64 box64-memory-patch
cd box64-memory-patch
# repeat build instructions

Yeah, I was doing something wrong. I rebuild the container with your version and it works. At least I have tried to start the server several times and it goes correctly all the times. As it's a random issue it's difficult to determinate that is fixed, but I think so.

I think that maybe can be merged the fix to the main repository?

Thanks so much!

[mogery]

Glad to hear that! The PR's ready from my side, just waiting for merge now.

[mogery]

@highland-joe could you verify that it also works for you? The PR has been merged so you should be able to just pull and rebuild.
